Why does agricultural research often fall short of addressing food insecurity challenges in sub-Saharan Africa? In this conversation with Ken Giller, we explore this wicked problem from a systems perspective examining the diverse drivers and experiences of smallholder farmers and the socio-ecological systems in which they are embedded.
Ken provides a nuanced look at agroecological solutions and argues that relying solely on nature-based solutions would be inadequate to address food security problems in Africa. We also talk about the huge diversity of farmers that can be found under the banner of smallholders, an in-depth examination of the “yield gap,” and what gets lost when translating research into practice.
